Q Is it possible to raise your IQ?
Intelligence is mostly hereditary. Intellectual ability grows until about age 16, and after that changes very little. Practicing various skills which are tested on IQ tests will increase your IQ score some, but it is not likely to increase your intelligence. Intelligence is basically the abilities to learn, to reason, to remember, to think abstractly, to problem-solve, etc. These abilities are very difficult to improve once you are an adult, though you may improve specific skills. E.g. you can improve basic mathematical skills by practicing them often and learning certain mathematical shortcuts, or you can learn to read faster by pushing your reading speed and learning to scan for meaning. Generally, the best way to improve your performance in specific work tasks is to do those tasks a lot. When you do that, you gradually learn the best possible techniques to efficiently and accurately complete that work, in the minimum necessary amount of time.
